SHOCK-ABSORBER.

T 0 all Vu'zom it may concern Be it known that we, HERMAN ll. SUN- voLDand IlxLroxx Lxusox, citizens o:t` the United States. residing at SacredHeart, in the county oit Renville and State of Minnesota, have inventedcertain new and useful Improvements in Shock Absorbers, ol which thefollowing is a specification. ret'- erence being had therein to theaccompanying drawing.

This invention relates to shock absorbers and has special reference to adevice which is provided with a spring which is adapted to reduce therebounding ot' an automobile, when the same is traveling over an unevensurface.

Another object of the invention is the production of a novel clampmeans` which so formed as to cause the strain oi the shock to be carriedby the frame of the automobile. A

lith these and other objects in view this invention consists ol certainnovel constructions, combinations, and arrangement ot' parts, as will behereinafter fully described and claimed.

In the accompanying drawings Figure l is a side elevation oit' thedevice attached to the frame of an automobile. Fig. 2 is a frontelevation of the device. Fig. 3 is a section taken on the line 3--3 ofFig. l. Fig. 4 is a section taken on the line 4-l of Fig. 2. Fig. 5 is aperspective view of the clamp.

Referring to the accompanying drawings it will be seen that the deviceconsists of a coil spring 1, which supports a strap Q upon thetransversely extending arm 3. The strap 2 is passed around the axle Llot' the automobile and in this manner provides a springing action whenthe car is being driven over uneven surfaces. The springl l is providedwith an upwardly extending neck 5 and terminates in a laterallyextending arm 6. y

A U-shaped clamp member, which is provided with the. jaws 7 is arried bythe :trame of the automobile. This U-shaped clamp is Specification ofLetters Patent.

held upon the trame by means of the screw S. which passes' through theaperture 9 formed in the lower jaw. said screw 8 bearing upon the frameot' the automobile and holding said frame in engagement with the upperjaw. A journal portion l0 is formed upon the upper jaw, which consistsof an enlarged body portion, which tapers down to produce a unitorn'ithickness along the .aide edges.

The laterally extending arm G passes through the aperture 11 formed inthe'journal it), and is held therein by means ofthe pin 12. By referringto Fig. 1, iny which the device is attached to the frame of theautomobile and axle thereof, it will be seen that the laterallyextending arm 6, which is posititmed within the aperture l1 formed inthe journal 10 of the clamp member, overhangs the traine of the car,whereby the strain occasioned by the car passing'over an uneven surfaceis carried directly to the trame, whereby the danger of breaking orwearing ot' the clamp member is greatly reduced, since said memberreceives comparatively little of the strain.

Having thus described the inventiomwhat is claimed as new is `In a shockabsorber of the class described adapted to straddle the angle iron of anautomobile con'iprising a spring, connecting means carried by thc lowerend of said spring, said spring provided with an upwardly extending neckterminating in a laterally extending arm, a U-shaped clamp memberadapted to he carried by the frame of the automobile, said clamp memberprovided with means tor holding it in engagement with said frame, ajournal formed upon the upper side ot said clamping member. said journalprovided with an enlarged body portion taperingto produce a uniformthickness along the side edges of the clamp` ing member, said bodyportion of said journal provided with a longitudinally extendingaperture. said laterally extending arm ot said spring positioned withinsaid aperture formed in said journal so as to overvholding the-laterallyextending arm therein,

wherebywhen'pressure is brought to bea-r upon the spring the strain willbe brought A to bear directly upon the frameof the automobile, and inthismanner greatly reduce the wear: upon the clamping member.

In testimonywhereof we hereunto aflix our signatures in presence of twowitnesses. 10
